The article "Use of Sunbeds or Sunlamps and Malignant Melanoma in Southern Sweden" , by J. Westerdahl et al. may be interesting reading. It appeared in VOl 140, No. 8 of the American Journal of Epidemiology in 1994, pp 691-699. The reference list is also quite good. Ken Price, RSO Univ. Conn. Health Center 75301.361@compuserve.co m
